Apart from page latches (buf_block_t::lock), mini-transactions are keeping track of at most one dict_index_t::lock and fil_space_t::latch at a time, and in a rare case, purge_sys.latch. Let us introduce interfaces for acquiring an index latch or a tablespace latch. In a later version, we may want to introduce mtr_t members for holding a latched dict_index_t* and fil_space_t*, and replace the remaining use of mtr_t::m_memo with std::set<buf_block_t*> or with a map<buf_block_t*,byte*> pointing to log records. |
